Give morphine or other central nervous system (CNS) depressors.
• Make any deep cuts at the bite site. Cutting opens capillaries that in turn open a direct route into the blood stream for venom and infection.
Note: If medical treatment is over one hour away, make an incision (no longer than 6 millimeters and no deeper than 3 millimeter) over each puncture, cutting just deep enough to enlarge the fang opening, but only through the first or second layer of skin. Place a suction cup over the bite so that you have a good vacuum seal. Suction the bite site 3 to 4 times. Use mouth suction only as a last resort and only if you do not have open sores in your mouth. Spit the envenomed blood out and rinse your mouth with water. This method will draw out 25 to 30 percent of the venom.
• Put your hands on your face or rub your eyes, as venom may be on your hands. Venom may cause blindness.
• Break open the large blisters that form around the bite site.
After caring for the victim as described above, take the following actions to minimize local effects:
• If infection appears, keep the wound open and clean.
• Use heat after 24 to 48 hours to help prevent the spread of local infection. Heat also helps to draw out an infection.
• Keep the wound covered with a dry, sterile dressing.
• Have the victim drink large amounts of fluids until the infection is gone.
Wounds
An interruption of the skin's integrity characterizes wounds. These wounds could be open wounds, skin diseases, frostbite, trench foot, and burns.
Open Wounds
Open wounds are serious in a survival situation, not only because of tissue damage and blood loss, but also because they may become infected. Bacteria on the object that made the wound, on the individual's skin and clothing, or on other foreign material or dirt that touches the wound may cause infection.
By taking proper care of the wound you can reduce further contamination and promote healing. Clean the wound as soon as possible after it occurs by-
• Removing or cutting clothing away from the wound.
• Always looking for an exit wound if a sharp object, gun shot, or projectile caused a wound.
• Thoroughly cleaning the skin around the wound.
• Rinsing (not scrubbing) the wound with large amounts of water under pressure. You can use fresh urine if water is not available.
The "open treatment" method is the safest way to manage wounds in survival situations. Do not try to close any wound by suturing or similar procedures. Leave the wound open to allow the drainage of any pus resulting from infection. As long as the wound can drain, it generally will not become life-threatening, regardless of how unpleasant it looks or smells. Cover the wound with a clean dressing. Place a bandage on the dressing to hold it in place. Change the dressing daily to check for infection.
If a wound is gaping, you can bring the edges together with adhesive tape cut in the form of a "butterfly" or "dumbbell" (Figure 4-7).
In a survival situation, some degree of wound infection is almost inevitable. Pain, swelling, and redness around the wound, increased temperature, and pus in the wound or on the dressing indicate infection is present.
To treat an infected wound-
• Place a warm, moist compress directly on the infected wound. Change the compress when it cools, keeping a warm compress on the wound for a total of 30 minutes. Apply the compresses three or four times daily.
• Drain the wound. Open and gently probe the infected wound with a sterile instrument.
• Dress and bandage the wound
• Drink a lot of water.
Continue this treatment daily until all signs of infection have disappeared. If you do not have antibiotics and the wound has become severely infected, does not heal, and ordinary debridement is impossible, consider maggot therapy, despite its hazards:
• Expose the wound to flies for one day and then cover it.
• Check daily for maggots
• Once maggots develop, keep wound covered but check daily.
• Remove all maggots when they have cleaned out all dead tissue and before they start on healthy tissue. Increased pain and bright red blood in the wound indicate that the maggots have reached healthy tissue.
• Flush the wound repeatedly with sterile water or fresh urine to remove the maggots.
• Check the wound every four hours for several days to ensure all maggots have been removed.
• Bandage the wound and treat it as any other wound. It should heal normally.
Skin Diseases and Ailments
Although boils, fungal infections, and rashes rarely develop into a serious health problem, they cause discomfort and you should treat them.
Boils
Apply warm compresses to bring the boil to a head. Then open the boil using a sterile knife, wire, needle, or similar item. Thoroughly clean out the pus using soap and water. Cover the boil site, checking it periodically to ensure no further infection develops.
Fungal Infections
Keep the skin clean and dry, and expose the infected area to as much sunlight as possible. Do not scratch the affected area. During the Southeast Asian conflict, soldiers used antifungal powders, lye soap, chlorine bleach, alcohol, vinegar, concentrated salt water, and iodine to treat fungal infections with varying degrees of success. As with any "unorthodox" method of treatment, use it with caution.
Rashes
To treat a skin rash effectively, first determine what is causing it. This determination may be difficult even in the best of situations. Observe the following rules to treat rashes:
• If it is moist, keep it dry.
• If it is dry, keep it moist.
• Do not scratch it.
Use a compress of vinegar or tannic acid derived from tea or from boiling acorns or the bark of a hardwood tree to dry weeping rashes. Keep dry rashes moist by rubbing a small amount of rendered animal fat or grease on the affected area.
Remember, treat rashes as open wounds and clean and dress them daily. There are many substances available to survivors in the wild or in captivity for use as antiseptics to treat wound:
• Iodine tablets. Use 5 to
